active edge of the cutter. Theenlarged er thickened portion 2O of thewasher forms a shoulder 22, which is disposed below the head 18 of thebolt so that when the cutter removes a chip or portion 23 from thesurface of the work 12, as shown in Figure 2, the chip will be deflectedaway from the head of the bolt 18 and will be prevented from passingunder the bolt, which would cause the chip or shaving to become brokenand the bolt head would operate as a stop to prevent the chip frompassing out of the machine, with the result tha" the machine wouldbecome clogged.

Arranged adjacent the cutter head 16 are upright bearing members 24,having slidable. bearings 25 mounted therein. Carried by the bottom ofeach of the bearings is an adjustable stop 26 adapted to engage a stop27 to limit the downward movement of the bearing 25. This movementobviously can be regulated by adjusting the screw or stop 26.

A spring 28 is arranged above the bearing 25, one end of which restsupon the bearing and the other end preferably against plate 29controlled by a screw SO., and )y means of which screw the tension orstress of the spring 2S upon the bearing 25 may be varied. One of thesebearings is arranged preferably at eac-h side of the cutter head.

A frame like structure 31 is pivotally mountd by one extremity in thebearings 25, and to that end there may be provided a bar or rod 82connected to the frame and journaled in the bearing.

This frame is preferably of a hollow construction, the side members ofwhich converge from the bearings 24 toward the front end of the machineand are connected at such end by means of a cross bar 33. A handle 34 issecured to the cross bar 33 and the side members are preferably of sucha length that the handle Se will project beyond the forward end of themachine so as to permit. the handle to be readily grasped by theoperator for the purpose of exerting pressure upon the frame 31.

A plurality of rollers 35 are journaled These rollers are provided withresilient peripheries and one of the rollers is preferably arranged inclose proximity to the cutter 17. lVith this construction it will bemanifest that the frame 31 may be swung about its pivot from theposition shown in dotted lines in Figure 1 to the position shown in fulllines in said ligure, thereby raising the rollers 35 to permit theinsertion or removal of the work 12.

lhen the work is placed upon the work support 11 with the forward edgeabutting the stop 13, the frame 31 is lowered from the position shown infull lines in Figure 1 to the postion shown in dotted lines in Figure 1.and in full lines in Figure 2, so that the rollers will rest against theback of the work 12. Pressure is then exerted upon the frame by graspingthe handle 34 to hold the work firmly upon the work support 11. Theperipheres of the rollers 35 being resilient or elastic will compensateany irregularities in the thickness of the plate and it will be manifestthat each of the rollers will engage and hold adjacent portions of theplate throughout substantially the entire area of the plate and whilethe plate is being advanced to the cutter the rollers will roll over theback surface of the plate.

The tension of the s )ring 28 is adjusted so as to hold the roller 35,which is adjacent the cutter 17, against the plate but may yield topermit the bearing 25 to slide in the bearing member 211 to compensateplates of different sizes. That is to say the spring 28 may be soadjusted to permit the holder 31 toaccommodate plates of varyingthicknesses within certain limits.

As a. means for holding the frame 31 elevated when the frame is movedinto the position shown in full lines in Figure 1, a counterbalancingweight 36 may be provided and this weight 3S is adjustably mounted uponan arm 3'?, which latter is secured in any suitable manner to the frame31, and ene of these counterbalancing arms 37 may be provided on eachside of the machine. The weight 36 serves as a means for assisting` inelevating the frame 3l.

A link 38 is pivotally connected as at 39 with a fixed portion of themachine, preferably to the cutter head 16 and is provided with anelongated slot 40 adjacent its other end. A pin or bolt` 41 passesthrough the slot 40 and is anchored or secured to the arm 57 so thatwhen the frame 31 is moved about its pivot 32, the pin or bolt 41 willslide back and forth in the slot 40, and at the same time the link 38will move about its pivot 39. This link and bolt and slot connection areprovided as a means for controlling or limiting the extent of pressurewhich may be exerted upon the work 12 when pressure is applied to thehandle 31 and is accomplished by reason of the fact that the bolt or pin41. will engage the end of the slot e0 in the free end of the link andthereby limit the downward movement of the frame 31. As a` means forvarying the extent of such movement there may be provided an adjustablestop or bolt 42 which is secured to the end of the link 38 and isadapted to be projected into the slot 40 to form an adjustable abutmentagainst which the bolt or pin 41 will strike.

After the holt or stop 42 has once been adjusted such an adjustment willcompensate for varying thicknesses of plates or work 12 withinpredetermined limits, as the valul) riation in thickness ot the workwill be turther compensated by the operation ot the spring 2S upon thebearing` Obviously one ot these link attachments may be applied to eachside ot the traine.

A shield l?) may be provided to extend over the roller 35 and also overthe pivot rod S2. This shield may be held in position iu any suitablemanner preterably by being secured as at -fl-lto one tace ot the traine3l and to that end the intermediate portion ot the shield all may be cutand deflected as shown in Figure lly use oil this shield it will bemanifest hat when the chip is cut 'trom the work shos-ru iu Figure L,and is detlecter by the beveled portion 2O ot the washer 19, the shield3 coopa-matin,L with the beveled surliace 2O ol the washer will causethe chip to curl over the shield and away Ytrom the cutten While thepretcrred t'orni ot the invention has been herein shown and described itis to he understood that various changes may be made in the detailsconstruction and in the combination and arrangement ol the seve ralparts, within the. scope ot the claims, without departing from thespirit ot this invention.
